"Alcohol Based Hand Sanitizers for the Prevention of Acute Diarrheal Disease and Acute Respiratory Infection in Children Under 5 Attending Childcare Centers in Bogotá, Cundinamarca and Tolima, in Colombia: a Cluster Randomized Control Trial"

We performed a cluster, RCT in child care centers located in six urban settings of Colombia with intermittent tap water availability. A total of 1727 children between 1 and 5 years of age distributed in 42 childcare centers participated in the study. The intervention consisted on installation of ABHS gel dispensers and training on their use by participating children in child care centers. Centers assigned to the control group were recommended to continue with current hand hygiene practices. Child care centers matched by location, size and sanitary conditions were randomly assigned to intervention or control. Cases of Acute Diarrheal Disease (ADD) and Acute Respiratory Infections ARI were identified through teacher reported signs and symptoms of disease and validated by a trained physician. We also monitored adverse events potentially related to ABHS. To compare incidence rates between study arms we modeled the number of episodes of ADD and ARI per child using a Cox proportional hazards multiple regression with random effects.
